This equipment is to be used only inside a building. It may only be connected to other equipment that is installed inside a building.

A balanced/unbalanced input selection button
Left and right level (gain) controls
Operation as a stand-alone distributor, or as a companion to other Kramer “50” series products like the VM-50V video DA, or the VM-50YC s-Video DA

The VM-50AN is housed in a desktop sized enclosure. Two units can be rack mounted side-by-side with the optional RK-1 adapter in a 1U rack space.
